Specification forming part of Letters Patent ,wrinkled; and to this end it consists in providing a flat belt with an internal longitudinal guiding rib to run in a corresponding groove in the roll or pulley, or with a groove to receive a flange upon the pulley or roll. The invention is designed more especially for use in connectionwithrubber or other elastic aprons used as conveyers in wool-washing and other similar machines, and which, passing between presser-rolls, are compressed and expanded laterally; but the improvement may be used to good advantage in connection with driving and other similar belts.

It is to be distinctly noted that my rib or groove is intended for and answers the sole purpose of a guide; that it does not constipart of the belt, but .is merely an addition thereto; and that, being very narrow as compared with the width of panding'and g laterally without wrinkling or order to give-an increased and arranged to run in corregrooves, the V-shaped port-ions forming the body, and extending the full width of thebelt.

In the various figures, A represents the belt or apron, and B. the roll upon which it is mounted. In Figs. 1 and 2 the belt is provided on its inner surface with a narrow longitudinal central rib, a, of a tapering or V form in cross-section, and the roll provided with a corresponding groove, b,.in which the rib is seated.

The rib is preferably made of the Vform and in one continuous unbroken length; but its sectional form may be modified, and it may be divided into short sect-ions or lengths, as represented hr Fig. 6, in order to enable it to of the roll or pulley. While it is preferred to locate the rib in the center of the belt, as shown, it may be located atQeither edge, or at any intermediate point desired. y

Referring to Figs. 3 and 4, it will be seen that the belt, instead of having a projecting rib, is provided in its inner face with a continuous longitudinal groove,'into which a corresponding rib on the roller enters, as shown, the arrangement being merely the reverse of that represented in Figs. 1 and 2, the mode of operation and .result secured being essentially the same under the two forms of construction. In ,cases where they can be used -to advantage two or more ribsor grooves may be employed in connection with the same belt; but where the belts are subject to a material lateral expansion only a single rib or groove canbeus'edp 3 I Having thus described myin'veniion, what "Irclai'm is- 1-; v i" i.
